Video: Present and Future Leadership Computers at OLCF

olcf

In this video from the 2015 OLCF User Meeting, Buddy Bland from Oak Ridge presents: Present and Future Leadership Computers at OLCF. “As the home of Titan, the fastest supercomputer in the USA, OLCF has an exciting future ahead with the 2017 deployment of the Summit supercomputer. Summit will deliver more than five times the computational performance of Titan’s 18,688 nodes, using only approximately 3,400 nodes when it arrives in 2017.”

GENCI to Collaborate with IBM in Race to Exascale

world

Today GENCI announced a collaboration with IBM aimed at speeding up the path to exascale computing. “The collaboration, planned to run for at least 18 months, focuses on readying complex scientific applications for systems under development expected to achieve more than 100 petaflops, a solid step forward on the path to exascale. Working closely with supercomputing experts from IBM, GENCI will have access to some of the most advanced high performance computing technologies stemming from the rapidly expanding OpenPOWER ecosystem.”

The Price of Open-source Software – a Joint Response

opensource

Should all academic software be released as open source by default? “Ultimately, we must accept that research is best served through using a combination of open-source and proprietary software, through developing new software and through the use of existing software. This approach allows the research community to focus on what is optimal for scientific discovery: the one point on which everyone in this debate agrees.”

Video: Stunning Simulation Shows Comet in the Solar Wind

In what has to be one of the most beautiful simulations I’ve ever seen, this video from the European Space Agency shows simulated interaction of solar winds with 67P/Churyumov-Gerasimenko, the famous comet targeted the Rosetta mission. “The simulated conditions represent those expected at 1.3 AU from the Sun, close to perihelion, where the comet is strongly active.”

ISC Cloud & Big Data Conference to Focus on Business, Technology and Research

iscCloud

Early Bird registration rates are now available for ISC Cloud & Big Data Conference, which takes place Sept. 28-30 in Frankfurt, Germany. This year the event will kick off with one full day of workshops. The new program will highlight performance demanding cloud and big data applications and technologies and will consist of three tracks: Business, Technology and Research.

Accelerating Science with SciDB from NERSC

Over at NERSC, Linda Vu writes that the SciDB open source database system is a powerful tool for helping scientists wrangle Big Data. “SciDB is an open source database system designed to store and analyze extremely large array-structured data—like pictures from light sources and telescopes, time-series data collected from sensors, spectral data produced by spectrometers and spectrographs, and graph-like structures that illustrate relationships between entities.”

NASA Charts Sea Level Rise

NASA visualization shows shifts in the Gulf Stream (in Blue). Yellow shows drops in Sea Levels while Orange shows increases.

“Sea level rise is one of the most visible signatures of our changing climate, and rising seas have profound impacts on our nation, our economy and all of humanity,” said Michael Freilich, director of NASA’s Earth Science Division. “By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes.”

Rescale Launches Cloud HPC Platform in Europe

Today Rescale announced availability of its Europe region simulation and HPC platforms. As an HPC cloud provider, Rescale offers a software platform and hardware infrastructure for companies to perform scientific and engineering simulations.

From Grand Challenges to Critical Workflows

Grand-Challenge-Blog-Part1

Geert Wenes writes in the Cray Blog that the next generation of Grand Challenges will focus on critical workflows for Exascale. “For every historical HPC grand challenge application, there is now a critical dependency on a series of other processing and analysis steps, data movement and communications that goes well beyond the pre- and post-processing of yore. It is iterative, sometimes synchronous (in situ) and generally more on an equal footing with the “main” application.”

China May Develop Two 100 Petaflop Machines Within a Year

“Within the next 12 months, China expects to be operating not one but two 100 Petaflop computers, each containing (different) Chinese-made processors, and both coming on stream about a year before the United States’ 100 Petaflop machines being developed under the Coral initiative. Ironically, the CPU for one machine appears very similar to a technology abandoned by the USA in 2007, and the US Government, through its export embargo, has encouraged China to develop its own accelerator for the other machine.”
